What is the equivalent of a 7303A-2RS bearing?

The 7303A-2RS is a 17×47×14mm angular contact ball bearing with verified equivalents across multiple brands: NSK 7303A-2RS, Timken 7303-2RS, FAG 7303-B-2RS-TVP, SKF 7303 BE-2RZP. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 7303A-2RS bearing?

The 7303A-2RS bearing has a bore diameter of 17mm, outer diameter of 47mm, and width of 14mm. It has a dynamic load rating of 12.15 kN, static load rating of 5.24 kN, and weighs 68g. Maximum speed with grease lubrication is 13,600 rpm.

Can I replace a NTN 7303A-2RS with a NSK equivalent?

Yes. NTN and NSK bearings with the same ISO designation are dimensionally interchangeable. The 7303A-2RS (17×47×14mm) can be replaced with the equivalent NSK part number as long as the seal type (2RS) and clearance class (CN) match. Always verify load ratings and speed limits for your specific application.
